Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Mon Sep 20 2021

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical 
Storm Peter, located northeast of the northernmost Leeward 
Islands, and on Tropical Storm Rose, located over the eastern 
tropical Atlantic Ocean.

Showers and thunderstorms associated with a tropical wave located
several hundred miles south of the Cabo Verde Islands are 
still showing some signs of organization, although there does not 
appear to be a surface circulation at this time.  Upper-level 
winds, however, are expected to become conducive for further 
development by midweek, and a tropical depression is likely to form 
by Thursday or Friday while the system moves westward at 10 to 15 
mph across the eastern and central tropical Atlantic Ocean.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...high...80 percent.

A storm-force, non-tropical low pressure system, the remnants 
of Odette, is located a few hundred miles southeast of 
Newfoundland.  This low could acquire some subtropical 
characteristics by the middle of this week as it moves slowly 
southeastward over warmer waters across the north-central Atlantic 
Ocean before moving northward over cooler waters over the weekend.  
Additional information on this system, including storm warnings, can 
be found in High Seas Forecasts issued by the National Weather 
Service.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...30 percent.
